A magnetic recording medium and a thin film planar magnetic head form an assembly. The magnetic recording medium of the assembly includes a magnetic coating having a residual magnetization value (Mr) and a thickness value (t) which together form a high product value (Mr)(t) which is preferably greater than about 1.8 memu/cm.sup.2. This coating also has a high coercive field value of Hc which is preferably greater than about 2,200 Oe. The ratio formed by dividing the (Mr)(t)product value by this coercive field value Hc((Mr)(t)/Hc) is preferably approximately 0.7.times.10.sup.-3 memu/cm.sup.2 /Oe or 0.8.times.10.sup.-3 memu/cm.sup.2 /Oe. The product of the (mr)(t) product value and the coercive field value Hc ((Mr)(t)(Hc)) is preferably greater than approximately 4000 Oe.times.memu/cm.sup.2. The overall effect of the present invention is to provide the magnetic medium coating with an enlarged hysteresis loop as compared to that conventionally used with such assemblies so that there is a resulting increased amplitude reading signal with an improved signal to noise ratio.

A working vehicle equipped with engine automatic stop device, having a vertically movable seat and an engine adapted to be stopped when the operator leaves the seat. There is disposed a restraining mechanism for preventing the engine from being stopped even though the operator leaves the seat when a clutch at a power take-out shaft is disengaged.
